Alcoholism and attention deficit disorder: MMPI correlates.

Previous research suggests that the alcoholic population can be meaningfully divided into subtypes, one of which is attention deficit disorder, residual type (ADDRT). The purpose of this study was to identify differences in personality profiles, as measured by the Minnesota Multiphasic Personality Inventory (MMPI), between ADDRT alcoholics and other alcoholics. Groups of 50 male ADDRT alcoholics and 50 male nonADDRT alcoholics were administered the MMPI. Statistically significant differences were found for the D, PD, Pa, Pt. Sc. MA, Si, F and K scales: the ADDRT alcoholics scored significantly higher than the nonADDRT alcoholics on most of the scales, but significantly lower on the K scale.
